This invention relates to sevvingzmachines, the object thereof beingdto provide :an "improved machine which, while particularly adapted for stitching powder :puffs, jmay also be used for stitching rpookets, bags,

Watch covers, pouches and other circular,

oral or similarly shaped articles 1 usually 'made by stitching together a plurality of superimposed layers of fabric Tin which the stitches extend completely or part way around the outer edges to leave an 'unstitched portion or opening 'suliicient to permitthe article to he turned inside out with velour fabric in which theplush -'or velour faces are juxtaposed forthe stitchi-ng'operation, and in which the stitch'linepreferably extends around the article a predetermined distance, thereby leaving an opening of about fifty degrees toper-mitthe article. to be turned inside out and thus bring the plush or velour faces on the outside, subsequent to which the unstitched portion is closedby hand stitching.

Another object of the present invention-is the provision of an improved machine-for stitching circular or similarly shaped articles and also irregular forms in a quick and Gilliciout manner and in which all that the'operator has to do is to place the work between circular clamp plates and depress a treadle, whereby the manual labor of operating the machine is reduced to a minimum andthe -r output of the machine materially increased, while a more uniform product is obtained.

A further object of theinvention is the provision of an improved "machine which will stitch circular or other similarlyshaped articles in such manner that the stitchingwill beraitrue-circle so as to leave a uniform amargnr from the stitch 11116 soithat whens-the "313131016 "1S *tturned rrnside :out there "will be ea uniform appearance wall around :the same and no objectionable bulking of :the -goods,

and in which machine the same number of -stit'ches is usedregar dless of the size of the article, and which machine is thIOWIljil'l'tO operation by the simple ypressure "upon a treadle and thereafter autolnati'oal-lyioperates to start the stitchnlgiatga predetermined point, and stopped ate-predetermined -:point with the needle out ofthe workandthew'vork released from'its clamp plateswith the' thread ends of the stitch 'lines of sufficient-length 4 to prevent rave'ling (back when the article is turned insideout.

A 'further object of i the invention is the provision of van improved machine-of the class described in which the superimposed pieces of workare so controlled as 'to'p'revent one layenthereof from "shiftingiupon the other, thus preventing puckering, gathering or -rundesi rable fullness of the stitched article. a

A further object. of the present invention is the provision of automatically opera-ted work clamp fp'lates, readily changeable for plates of idii-Perent diameters, together with meansfor circularly feeding "said plates and -wh1ch plates are mounted ona swinging I bracket whereby different sizes of work may fbe readily and uniformly stitched, and which is combined with a cylindersewing machine in such manner that-all that is necessary for the operator to do isto press: thertfoot treadle or other-means which may be used for starting the machine, whereupon the machine "starts and completes thewstitching of the circular form and stops at a predetermined position with: the; needle "out of the workand the work automatically unclamped-so that the operator merely removesthe stitched article and .places'the'next article in position for stitching. at "which time the threads-of the previously stitchedarticle are: automatically clipped by a cutter adjacent to the stitching position of the needle.

"In thespr'esent improved machine, which may be arranged :Eor making any desired ussmms To, METROPOLITAN siiwmG'MAcHiNn lOil form of stitch including a single thread chain or a two thread chain stitch, andhave a suitable automatic tension release to release the thread, the organization is such that there is always a' given number of stitches used in the stitching of each article regardless of its size or diameter, as the length of the stitches increases withthe diameter of the article so that, for instance, if 300 stitches are placed in a three inch powder puff, the same number of stitcheswill be placed ina three and a half I or four inch powder puff, and this has considerable to do with the output of the machine, for otherwise it would takelonger to stitch a large powder puff than a small one. Furthermore the application of this improvement to a cylinder machine'very materially increases the convenience in handling the work, the threading, cleaning and oiling, and so far as I am. aware this is the first cylinder sewing machine adapted for the circular stitching of the articles hereinbefore mentioned.

' Before explaining in detail the present improvement and mode of operationthereof, I desire to have it understood that the invention is not limited to .the details of construc-' tion and arrangement of parts whichare illustrated in the accompanylng drawings,

' since the invention is capable of other embodiments, and that the phraseology which I employ is for thepurpose of description and not of limitation.

. The present improvement is illustrated in connection with the well known Metropolitan cylinder sewing machines heretofore patented to me for instance in Patents No. 1,348,527, dated August 3, .1920, No. 1,352,333 dated September 7, 1920, andPatent No. 1,581,764,

dated April 20, 1926, and which cylinder machine ,offersimportant advantages in that the entire mechanism for operating the needle, looper and feed is carried in the trunk of the machine frame remote from these elements, thus providing ample space for con venience in handling the work as wellas offering other advantages that will appear in this specification.

This cylinder machine is equipped with automatic starting and stopping mechanism, automatic lubricating mechanism and automatic'thread control, and the novel features of the present invention reside principally in the rotary work clamp and its feeding mechanism, thread cutter and automatic operation of the machine and the associated parts necessary to apply the same to a cylin- ,der sewing machine- In the drawings accompanying and forming apart of this specification, the sewing machine frame includes a trunk 1 having a pair of forwardly projecting arms, one an overhanging arm and the other shown as a cylinder, and this trunk carries a handwheel 2 for turnlng the machine operating parts by.

hand. A beltguard 3 encloses the belt 4 which is operated by a transmitter, indicated generally by '5, see Fig. 3, comprising a tight and a loose pulley or clutch. A rod 6 is connected to a foot treadle 7 pivoted at 8 to a support 9 secured to the fioor. The forward end 10 of the foot treadle is manipulated by thefoot ofthe operator. Underneaththis treadle is alspring' I'l in'po's ition to. force the treadle u award. An suitablesnriiig ma i as .7

A rod 1d is-aiso connected to. the control lever by adjustable collars 15 and forms the connectingmeans ates freely throughthis tableandis pro ided with a notch 19 for the purpose hereinafterdescribed, and by meansot a coupling :30 the upper end of this rod is connected with the lower end 'ofa rod 21. This rod has a sliding connection with the stop-1nd tion mechanism of the sewing machine which is fully described in the patents to. which reference has hereinbefore been made, and which includes a stopmotion lever pivotedto the trunk at 22.

Attached to the frontwall of the machine.

trunk are bearings 23, see Figs. 2 and 3. A vertical shaft 24 is mounted in these hearings and supports a swinging frame or bracket A which is likewise provided with bearings 25 and This frame swings freely on shaft 24.

down movement and also for rotation. The

upper end of this bar is provided with a Gen ter 30, see Figs. 3 and 8a, in which is seat-ed a ball 31. The forward end of the presser bar spring presses the bar 29 downward. A ball w ight 32a mounted directly onftop of the bar 29 may be used in place of this spring. The advanta e of the weight is that the pressure is uniform, whereas with'the spring there is a slight increase in tension as the bar is lifted. in order that the bar may have a vertical movement of about 1 inches and yet have a minimum variation in tension, the spring when used is provided with a loop 33 which gives a greateryieh ing action, so that the tension of the spring is unchanged when the baris either upor down. To regulate the pressure of the spring, an adjusting screw Si tapped into a lug carried by the swinging framefls provided. The rear end of the spring rests on the top of the vertical shaft 24-. To lift the presser bar 29, the upper end of stop mo-- tion operating rod 21 is employed to act remain in operative. .relatien. end ofthe lever 3'1" which'cooperates with the The forward end of this frame.

This disk l i may be provided with openings 45a to give a better gripping action on the work and thus prevent the work from slipping betweenthe work clamp plates This also permits a lighter pressure to be used. Y {r The hub l5 may be provided'with a set screw 45 to clamp'it in po'sitionf Thisclamp plate is; similar to the bottom work clamp plate 46 which is also provided with a hub 47 anda set-screw for securing it in position. Tie bottom plate is also carried on the tapered end 48 of a shaft'49. This shaft is rotatablein bearings SQand 51, which are part of the swin ing frame A. I These bean ings aresupportedand connected by a web formed bracket 52of the swing" igframe A forming a rectangular opening in which is located the feed mechanism 53 forrotating the clamp plates or work turntable.

Extending forwardly of this webbed bracket 52 is a work supporting bracket 54 to which is secured a work table 55, Which is changed when the work plates are-changed for larger or smaller diameter plates. The table has a semicircular cutout portion conforming to the work plate. [These work tables are made in different sizes to suit the character ,of article to be stitched by' the machine, as

for instance a 2-inch diameter work clamp platewould require one size of work table int while a 5-inch work clamp plate would require a larger size of work table. Different sizesand diameters of plates are provided to suit thesize, shape or kind of work required. Since these tables have to be changed frequently, 7 fastening means 56 therefor is provided so that they maybe quickly attached or removed; and since the rotary work clamps'or plates Mandflfi havealso to be changedfor different sizes ofarticles, it is desirable to have them arranged for quick attachment and removal. Any means such as the taper and set screws described and Which can be quickly manipulated to facilitate their adjustment to a fixed position relative to theother-parts, may be used, as the changing of these'parts is usually done by the machine operator. 7 V 1 Fixed to the lower end of the shaft 49, see Figs .3, 5 and 8, is a gear 57 in mesh with and operating a gear 58 pivotally secured to the under side of the swinging frame A by means of an adjustable stud 59. This gear 58 carries a pin 60 projecting downward which coacts with a roller ,61 carried by a stud 62 secured to a lever 63 pivoted at 64 to the swinging frame A.

To the upper end of this lever 63 as at 65 is secured a trip mace which is under the control ofaspring 67, one end being iconnected thereto and the other end connected as at 68 to the'machine frame. The rear end of the rod 66 is bentdownward as at 69, and

has pivotally connected thereto a slide bar which isslidably supported-in thebottom of the machine trunk- The rear toothed end 71 of. this slide is in position to engagethe notch 19 of the rod 14. The slide is so located as to have the center of its bentend 69 in line with the vertical axis of the shaft 24 so that the swinging frame A may swing in and out toward and from the cylinder without binding or cramping the trip rod 66. The normal tension of thespring 67 keeps the ends 71 of the slide 70 against the rod 14 so as to shift into the notch 19 instantly as the rod 14 is depressed at the time the machine is started, thus maintaining the machine in operation until the pin 60 carried by the gear 58 makes a complete revolution, at which timethe trip mechanism will be operated, and the end 71 of this trip slide will be withdrawn from the notch 19 and the machine stopped by the stop motion mechanism.

If gear 58 is smaller in diameter than the gear 57, it will make a complete revolution proportionately faster and thereby trip the stop motion rod 14 by withdrawing the toothed end 71 thereof from the notch 19. The treadle spring '11 cooperating with the stop lever springs thereupon acts to force the rods 6, 14 and 21 upward and bring the machine to a stop. Ben the otherhand it IS desired to havethe'machine stitch completely around a circle, both gears 57 and 58 would have the same diameter; orif it is desired to have the stitches overlap after stitching the complete circle for about A or inch, then the gear 57 would ameter than would be the gear 58.

d The ratio of thesegears governsthe. distance of the stitch line around the article,

either to leave an unstitched' opening or to overlap the stitching to secure the beginning and ending of the stitch line, as the case may require.

The circular feed mechanism shown herein has a ratchet mechanism 53, see Figs. 1, 5, 5a and 6, is secured to theshaft 49 andposibe a trifle smaller in dicomprises-a feed wheel 72 recessed at 73 to receive a ratchet lever 74 having a'hub 75 telescoping the hub 76 of the feed wheel. The ratchet lever hub has a flange 77, see Fig. 5a, and also a flange 78 terminating in a lever end,7 9 connected to an arm orlever 80 by a bolt 81. This ratchet feed lever 74 carries four feed pawls 82 freely pivoted between theflanges 77 and 78 on pins 83. Connected to each pawl is a tension spring 84,

the other end of which is connected also to a pin carried by the feed lever. These four pawls grip the feed wheel so as to positively shift it step by step to properly space the stitches. To prevent back drag or slippage, a back lash pawl or dog 85, under the control of a pull spring 85a, see Fig. 8, is pivoted at 86 to the swinging frame A. This pivot 86 is in the form of an eccentric stud which thus provides a means of adjustment for the back lash pawl. The feed wheel 72 is provided with a metal cover 88 to prevent lint and dirt from interfering with the action of the feed pawls.

The intermittent feed-is operated by the feed bar located in the cylinder-of the machine and for this purpose a lever 89 having forked ends 90 engages the lever 80 of the ratchet feed. 7 The upper end of the lever 89 is bent at right anglesand has its bent end 92 secured to the feed bar 93 supported in the cylindrical arm or cylinder 94 of the machine by a link 95, see Fig. 13. The rear end of this bar is pivotally connected at 96 to a feed operating lever 97 which slidingly engages fulcrum 98. The upper end of the feed. lever 97 is connected with the crank arm of a crank shaft 99. The vertical post 100, see Fig. 13, contains an adjusting mechanism for raising" and lowering the fulcrum 98 to lengthenor shorten the throw ofthe feed bar WhlCll in turn lengthens or shortens the movement of the circular feed, thereby changing luv movable knife orbladejterminateslinaforked end 1 0 engaging, awpin lllharried by, the Q forward-endor thefeed..bar.93.

To hold the swingingfraineA, inwork-ing' positlon relative to the needle, eltheri a slotted link 112, see-Fig, 1,.or, a spring llti, see Fig. 14, attached toacollar, 113'is used. This .collar is clampledon the' -cylinder 9d. The link. is adjustably secured in position by a clamp screw 114,,see Fig-.1. The otherend of the link is connected, as at1 1'5,to the bottomo'f:

of this guide. In. fact, .afterthe operators 1 becomeexperienced, these guides; are: usually removed entirely from' the machine; The 1 setting of! the, work is then gauged entirelyv by the work clamp. As a matter, offfact',the

' guidepositioned as shown in Fig. :8. could be used when stitching an articlelike Fig. since the guide would serve to locate the c 're cular portion ofthe article, while the work is being placed between the clamp plates. 2

;Attached to the'cylinder ofthe machine 1s a suitable gum-d125, seedottedilines F 1,-

which serves. not only to guard a part of'the feedmechanismdbut also. acts asa shelf or rest for the stitched powder puff or other ar ticle after it is completed and upon'which it I rests until the thread X,see 4, is severed into a suitable receptacle. 1 r V The operation ofthe machine is as follows:

"Elie operator assembles the sect-ions ofthe powderpulfor other article and placesthem inposition-on the lower work clamp or plate.

46st which time the top clainpplate. 14 is in itsuppermost-position (about 1 inch space.

whereupon the'transmitterclutch is. thrown into operation, being; driven. from agsuitablesource-of. powenas a;motor,anol operates the t-er s multan s rr thi s im he 1-ods l4 21 are shifted downward, thus menced, whereupon stitched article is red releasing the upper clamp plate and per mitting, its spring 83' or weight 32a to shift this plate, downward and clamp the work,

1 whereupon the clutch of the sewing machine shaft engages'and the machine starts the feeding and sewing. The trip pin carried by the gear 58 rotates away from the '7 highest position.

' The upward movement of the rod 21 shifts the levers 37 and 4e2'on'their pivots 38 and 41,

roller 61, thus, causing spring 67 to shift the slide so that its toothed end "71 engages the notch or tooth 19, of the rod 14 and'holds it downwhereupon the operator may remove his foot from the treadle 10 since the machine,

continues to operate until the pin 60 makes a complete, rotation and operates the trip mechanism to release the. toothed end 71 of theaslide ba'rifrom the notch 19. In other words the machine stitches the circle until the pin 60 rota-tes into engagement with the roller 61 which thus shifts the lever 63 and parts to their normal upward position, the

transmitter clutch is disengaged, the sewing machine clutch is also disengaged and the machine stops instantly with the needle at its so as to lift the top work clamp 44 against the action of the spring 33 orfagainst the pressure of the weighted ball 32a, .when this is used in n place of the spring 33. The'stitched article is then removed to the left and another ar- .ticle placed for'stitching. Instantly as the machine starts the thread or chain of stitches indicated byX in-Fig; 4 is brought into en- 1 gagement with the knife 108 and severed thereby.

From the foregoing it will be understood that the operation of stitching circular or irregular forms merely requires-the placing of the work in position between the clamp plates and pressing the treadle to start the gardless of shape, size or diameter of the articles being stitched. Byreason of these ically, whereupon the operator merely removes the stitched article and places the next articles in position for stitching. The chain of stitches or threads at the end of-the stitching operation is automatically clipped by a cutter located adjacent to the needle as the stitching of a succeeding article is commoved'or falls into'a suitable receptacle.

From the foregoing it will be observed that a; single treadle controls the entire operation of the machine and that'by pressing this article sewed whereupon at a predetermined time the trip mechanism releases the rod 1 1 and the ,machine is automatically stopped whereupon the work is automatically unclamped. v I j In this improved machine it will be observed that the work clampsj will be rotated as long as the machine is keptin' motion since the release of the work clamps takes place only after the machine is stopped, In other words, continued pressure upon thetreadle will maintain the machine in continuous oporation if desired, whereas should a separate treadle be used'to control the work clamps, the inadvertent manipulation of this treadle would result in theimmediate unclamping of the work while the machine was in motion so that the work would -cease to rotate andth'e stitches pileup, whereas in the present imrovement' the machine and the operation thereof is underthe controlfof a single element or treadle.

In practice the operating belt i could rundirectly to a suitable source of power and the transmitter entirely done away with since the'crank shaftof the sewing machine con- V tains a clutchlasset'forth in the patentshereinbefore referred to, in which casethe rod'G would be coupleddirectly to the rod let. In

suclrinstance, the belt 4. would "be in continuous operation but themachinewould start and stop precisely as though the transmitter wereus'ed'. v v r It is to be understood that by describing in detail herein any particular form, struc ture or arrangement, it is not intended to limit the inventionbeyond the terms of the several claims 'or the requirements of the prior art. i v
